The mmsys driver is now the top level entry point for the multimedia
system (mmsys), we bind the clock driver by creating a platform device.
We also bind the MediaTek DRM driver which is not yet implement and
therefor will errror out for now.

You may need to let CONFIG_MTK_MMSYS depends on
CONFIG_COMMON_CLK_MT8173_MMSYS || CONFIG_COMMON_CLK_MT8183_MMSYS

That will be fixed by:
https://patchwork.kernel.org/patch/11469521/

Otherwise this won't scale as we would need to add the SoCs using the mtk-mmsys
driver and this will be a lot if not all.

Matthias
